. This invention relates to Windows.

It is among theobjectsof the present invent on to provide a novel and'improved window having reciprocating and pivotally movable sashes. a

, A further object of the present invention is to provide in a window, a sash slidably mounted upon vertical rods pivotally movable with respect to the window frame, whereby the sash may be moved out from the confines of the window frame. y

, A further object of thepresent invention is to provide a windowincluding vertically movable sashes, together with novel means for locking the sashes in adjusted position.

1. In conneetion with the present invention, it will be seen that the device is particularly ada ted to provide facility in cleaning the windowand for painting or repairs thereof, the arrangement being such that both of the sashes of the window may be pivotally moved to rovide clear access to the window.

The invention further provides this novel pivotal feature in combination with sashes capable of novel verticalinovement.

Further objects of thepresent invention include the novel and improved interrelation of parts whereby the whole forms a simple and eflicient structure readily designed to meet the demands of economic manufacture. Other obiects of the presentinvention will be apparent f om a consideration of thefollowing specification taken in coniunction Figure 1 isan elevationalview of the in ter or. of one form of the present invention;

1 Referring more particularly to the draw ings, the present invention is shown in combination with. a window frame, generally indicated by the numeral 10. Within the frame 10, upper and lower window sashes 11 and12, respectively, are mounted. The upper and lower sashes are supported for vertical movement by angular guide and supporting bars 13 and 1 1, respectively. The 65 view showing the lower guide bar 13 of the upper sash is supported a in a hinged bracket 15 illustrated in detail in Fig.8. f Thebracket 15 includes an angular socket 16, which is adapted to receive therein the bar 13. and further includes a plate 17 to which the socket 16 is pivotally secured. The plate 17 is adapted to be secured to the side of the frame, as indicated in Fig. 2. 'Thepreferred arrangement, as illustrated in Fig. 1, includes an upper and a lower terminal bracket 15 for the upper bar 13 as well as an intermediate bracketthrough which the bar passes. The end brackets are adapted to receive the terminal ends of the bar 13.

"For permitting vertical'movement of the upper sash 11 over the bar 13, one-or more tubular rigid sleeves 18 are providedcarried by the side rails of the sash. The sleeves 18 are rigidly secured to the sash and, as illustrated in Fig. 10, include a leaf spring 19,

the ends of which extend over the bracket on the rail applied by the spring 19. By

this arrangement, counterweights for the sashes are not required, as the spring construction provides for frictional contact whereby the sashes will retain their adjusted position. For positively locking the sashes, a central screw 21 is provided, which has threaded connection through one wall of the sleeve 18, the arrangement being such that adjustment of the screw 21 provides for securement of the sleeve to the bar and against normal vertical movement thereof.

The lower sash 12 is mounted for movement over its rod 14 through a bracket 18 similar to that used for the upper sash. The rod 14 of the lower sash is pivotally connectedto the frame 10 by a double bracket, as shown in Fig. 7. The double bracket-includes a plate 22, which is secured in suitable manner to the frame 10 and an intermediate plate 23pivoted thereto. The opposite edge of the intermediate plate is pivotally associated with the rod receiving socket 24. As indicated in Figs. '6 and 9, this arrangement of parts provides for the lower sash swinging outwardly, as shown by the dotted lines in Fig. 2, through the pivotal movement of the socket 24 with respect to the intermediate plate 23. Thelower sash 12 is also pivotally moved by respective movement between the intermediate plate 23 and the securing plate 22, whereby the sash lies in the fully opened position parallel to the inner wall, also as indicated'in 2.

For preventing pivotalmovement of the upper sash 11 while it is in its raised position, a spacer bar '25 is provided, which extends downwardly toward the lower sash, terminating above the central portion of the window frame. By this arrangement, it will be seen that when the lower sash has been opened, the upper sash may be moved downwardly below the lower end of the spacer bar 25 and may then be pivotally moved by pivotal movement of its bar 13, as indicated in Fig. 5.

In the operation of the device, it will be seen, that both the sashes are freely movable within the frame 10 by movement of their sleeves 18 over theirsupporting rods. The movement of the sle'evesoverthe rods is against the normal friction imposed by the spring 19 of the sleeves, and thus the sashes will maintain their adjusted positions. When it is desired to lock the sashes in adjusted positions, the screw 21 is tightened, whereby its inner end embracesthe supporting. bar, thus preventing movement of the sleeve with respect to the bar.

It will further be seen that in addition to the normal vertical movement of the sashes, they maybe pivotally movecl by the pivotal mounting of their bars 18 and 14 through the bar supporting sockets. One of the sashes is'provided with a double. pivoted socket, whereby the sash may be swung to a fully opened position parallel with the wall of the building. It will further be seen that the spacer bar 25 provides means for preventing pivotal movement of the upper sash 11 except when such sash is below the center of the window. Equivalent means may be provided for controlling the pivotal movement of the lower sash 12.

From the foregoing it will be seen that the present invention provides a novel and efficient structure particularly adapted to meet the demands of economic manufacture. It will further be understood that the invention is not specifically confined to the detail structural features as herein presented, but that numerous changes,-modifications and the full useof equivalents may be resorted to without departing from the spirit or scope of the invention as outlined in the appended claims.

What is claimed is:

1. A window assembly, including a frame, rods hingedly supported by said frame, and sashes movable within said frame over said rods.

2. A window assembly, including a frame, rods hingedly supported by said frame, sashesmovable within said frame over said rods, said sashes including sleeves movable over said rods and manually actuated means for locking said sleeves to said rods.

3. A window assembly, including a frame, a vertical rod, means for pivotally supporting said rod from said frame, and a sash associated with said rod for vertical movement 1 thereover, said means including a socket for said rod and a hingedly associated base adapted'tobe rigidlysecured to.said frame, said socket further-including an intermediate plate whereby said sash may be swung from said position within said frame to an external position parallel to its normal position within said frame.

4. A window assembly, including a frame,

a pair of vertically movable sashes within said frame, and a pair of supporting rods for said sashes pivotally secured to said frame, said sashes including sleeves movable over-said rods by movement of said sashes, said sleeves including frictionalmeans for retaining said sashes in adjusted position. 5. A window assembly, including a frame, a pair of vertically movable sashes within said frame, a'pair of supporting rods for said sashes pivotally secured to said frame, said sashes including sleeves movable over said rods bv movement of said sashes, said sleeves including frictional means for retaining said sashes in adjusted position, and positive locking means for retaining said sashes in adjusted position.

6. A window assembly, including a frame. a pair of vertically movable sashes within said frame, a pair of supporting rods for said sashes pivotally secured to said frame, said sashes including'sleeves movable over said rods by movement of said sashes, said sleeves including frictional means for retaining said sashes in adjusted position, and positive locking means for retaining said sashes in adjusted position and a support mounted upon said frame in hack of the normal position of one of said sashes whereby said sash is prevented from pivotal movement with its rod when in normal position.
